Specification of Letters Patent.

Patented June 8, 1915.

Application filed September 16, 1912. Serial No. 720,525.

To all whom it may concern:

Be it known that I, GEORGE W. HoPKINs, a citizen of the United States,residingat Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Burners, of which thefollowing is a specification.

This invention relates generally to burners and particularly to suchdevices utilized for burning acetylene gas.

More specifically the invention relates to a hollow body or mixingportion integral with and forming a part of burner sections which arepreferably arranged at substantially right angles to the main bodyportion and are parallel with respect to each other, each of said burnersections having sides inclining inward with upper burner edges inclinedtoward a burner orifice which is arranged in the section, it being animportant feature to have the burner integral and of cast metal toprovide for heat conduction from the metal about the burner orifice.

Further invention resides in certain webbing between the parallel burnersections to provide for the radiation of heat from the innermostsections and further to suitable supporting lugs cast integral with theburner serving to radiate the heat from the webs; and still further to amounting for the burner whereby heat from the burner is transmitted tothe frame.

The invention may be further briefly summarized as consisting in theconstruction and combination of parts hereinafter set forth in thefollowing description, drawings and claims.

Referring to the drawings, Figure 1 is a top plan view of a burner; Fig.2 is a section upon the line 22 of Flg. 1; Fig. 3 1s a section upon theline 3-8 of Fig. 1; Fig. 4: is a longitudinal section through one of theburner sections; Fig. 5 is a side elevation of a portion of theframework of the stove showing the mounting of a preferred form ofburner; Fig. 6 is a bottom plan view of this preferred form of burner,and Fig. 7 1s a section upon the line 7-7 of Fig. 5.

In carrying out the invention any pre ferred form and construction ofparts may be employed so long as they possess the necessarycharacteristics, but I have shown two forms in the drawings, and in oneembodiment, 1 represents the main body portion or mixing tube having arestricted portion 2 near the outer end thereof and connected to asuitable wind shield 3. The main body portion is provided with aplurality of burner sections 4 having inclined sides 5 merging intosides 6 having a different degree of inclination and extending to apoint adjacent to a burner orifice 7 in the upper longitudinal edge.Each of the burner sections is provided with an opening 8 communicatingwith the opening in the main body portion 1 of the burner and furnishingmeans for supplying gas to each of the burner sections. Each of theburner sections may be provided with a web 9 formed integral with thesides of the burner section and extending across the same underneath theburner orifice, thereby furnishing means for holding the sides of theburner section next to the orifice at the proper distance apart, andfurther tending to break up the continuous flame which would otherwiseissue from the section. The burner sections 4 are secured together attheir ends by suitable webs 10 which furnish means for transmitting theheat from section to section. The burner is still further provided withlugs 11 which are integral with the end burner section near its endswhich forms a supporting means and also conveys the heat from the burnerto the frame of the stove. The burner may be mounted in still anothermanner in which case a bracket 12 is secured to the underside of theupper framework 13 of the stove and has a portion 14 extending under theopening in the frame and is provided with a longitudinal slot 15 forreceiving a longitudinal web 17 cast along the underside of the mainbody portion 1 of the burner. The burner sections may also be providedwith suitable radiating fins or webs 18.

The integral structure of the burner and the peculiar shape as set forthis of the greatest importance in acetylene burners by reason of the factthat with it there is a large releasing area'for the gas and air and atthe same time the heat is radiated from the burner so that thedecomposition of the acetylene gas by reason of the heat of the burneris avoided.

Having described my invention, I claim 1. A burner for acetylene gascomprising a frame, a body portion, integral burner sections arrangedparallel and transverse with respect to the body portion and havinginclined upper sides meeting at an apex and also having a gas slot ateach apex, means burner to the frame.

2. In a burner 7. structure for acetylene V formed integral with theburner sections for radiating the heat from one to the other, andintegral means forming part of the burner for radiating the heat fromthe comprising a frame, a body portion, a'plurality of parallelburnersections formed integral With the body portion, a radiating ribCopies of this patent maybe obtained for in presence of cast Withthemain body portion, and means 10 five cents each, by addressing theCommissioner ofiatentl, Washington, D. G.
